What is the best way to evaluate letter grades to your students?
In high school, there are A, B, C, D and F; and they assign a minimum of 90, 80, 75, 70 to all of them respectively. However in college, professors have the right to assign letter grades however they want to. In your opinion, what is the most accurate way to evaluate letter grades to your students? For example, by calculating normalized scores ((grade – avg)/standardDeviation), etc.

For myself, I would never recommend a normalized score based on standard deviation, mean, median, etc. There are inherent mathematical difficulties that come about when certain very high or very low scores skew the mean and make those normalized averages somewhat inaccurate.
If you simply want to use them as a rough guideline for your viewing, and then place the highest and lowest scores where you really want them to be (such as an A and a D-), that is fine.

I do 90, 80, 70, 60…mostly because I’m lazy, and this is easy for me and students to remember. Most score distributions are negatively skewed anyway, especially at the college level.

100-93 A
93-86 B
86-76 C
76-70 D
or do a bell curve but that means that some one allways fails. I would stick to a standard so no one can come back and say that you were unfair.
